Consent and Prerequisite. This part confirms participants' consent to participate in this survey and agreement to process their data.


Participants' Information. In this part, we collect participants' information such as experience, current profession, organization, country, and editing experience in SO posts.


Workload Assessment. This section assesses the cognitive workload of the control and treatment groups in suggesting edits to SO posts. We leverage the NASA Task Load Index (TLX) (non-weighted) to estimate subjective workload [1]}, [2]}, [3]}, [4]}. In particular, we assess how much effort participants had to exert mentally and physically to use EditEx and the standard edit system of SO. Participants were asked to rate their scores on an interval scale ranging from low (1) to high (10) [5]} in the following six dimensions – (1) mental demand, (2) physical demand, (3) temporal demand, (4) effort, (5) performance, and (6) frustration.


Usefulness Analysis. In this section, we measure the participants' confidence in suggesting edits using EditEx (treatment group) and SO edit system (control group). In addition, we ask the treatment group to rate the usefulness of the suggestions of EditEx. In particular, we ask the following two questions to the treatment group participants and employ a 5-point Likert scale (i.e., 1–5) to estimate their consent [6]}, [7]}.


How useful did you find the suggestions from EditEx? (5-point Likert scale)

How confident were you to follow the EditEx suggestions? (5-point Likert)

We ask the following question to measure the confidence level of the participants in the control group.

How confident are you to edit posts using the SO editing system? (5-point Likert scale)



Suggestions to Improve EditEx. Finally, we seek participants' recommendations to improve the effectiveness of EditEx. We ask them the question as follows.
